“…For instance, in actual power system, hyperchaos may result in blackout or catastrophic voltage collapse. 36 In such cases, these hyperchaotic behaviors need to be controlled. Hyperchaos control method has been widely studied by researchers and there are many valuable chaos control methods have been obtained.…”

Firstly, a novel six-dimensional (6D) hyperchaotic particle motion system is formulated. The equilibrium points and their characteristics, Poincaré sections, Lyapunov exponents, bifurcations and multi-periodic windows are studied. Secondly, we present two nonholonomic constrained systems. In order to analyze the particle motion trajectories under constraints, the explicit equations for constrained systems are given. Based on Lyapunov exponents, Poincaré maps and bifurcations, we can see that the different hyperchaotic phenomena of the particle motion can be generated by introducing nonholonomic constraints. Finally, the stability control of the 6D hyperchaotic particle motion system is realized by separately using constraint control method and linear feedback control method. Numerical simulations of the dynamical behaviors of the six-dimensional hyperchaotic particle motion system are carried out in order to illustrate the complex phenomena of the systems and verify the analysis results.

“…To avoid the influence of mismatched disturbances on control accuracy, Wang et al (2020) proposed a mismatched disturbance observer which could theoretically observe disturbances with arbitrary accuracy. The SMC proposed by Yang et al (2013) approached for systems with mismatched uncertainties via a nonlinear disturbance observer.…”

Purpose This paper aims to present a novel adaptive sliding mode control (ASMC) method based on the predefined performance barrier function for reusable launch vehicle under attitude constraints and mismatched disturbances. Design/methodology/approach A novel ASMC based on barrier function is adopted to deal with matched and mismatched disturbances. The upper bounds of the disturbances are not required to be known in advance. Meanwhile, a predefined performance function (PPF) with prescribed convergence time is used to adjust the boundary of the barrier function. The transient performance, including the overshoot, convergence rate and settling time, as well as the steady-state performance of the attitude tracking error are retained in the predetermined region under the barrier function and PPF. The stability of the proposed control method is analyzed via Lyapunov method. Findings In contrast to conventional adaptive back-stepping methods, the proposed method is comparatively simple and effective which does not need to disassemble the control system into multiple first-order systems. The proposed barrier function based on PPF can adjust not only the switching gain in an adaptive way but also the convergence time and steady-state error. And the efficiency of the proposed method is illustrated by conducting numerical simulations. Originality/value A novel barrier function based ASMC method is proposed to fit in the amplitude of the mismatched and matched disturbances. The transient and steady-state performance of attitude tracking error can be selected as prior control parameters.

“…Active Disturbance Rejection Control (ADRC), with Extended State Observer (ESO) at its core, offers certain advantages in dealing with complex, high-order, time-varying, nonlinear, and coupled systems without relying on the precise model of the controlled object. In reference [6] , an ESO-based sliding mode variable structure controller was proposed to suppress chaotic oscillations in a seventh-order chaotic power system. Reference [7] proposed a double closed-loop control scheme for the output series Boost converter by combining super-twisting sliding mode control and ADRC.…”

To reduce cross-coupling effects and enhance the dynamic response of the Single-Inductor Dual-Output (SIDO) Buck converter, this paper introduces an active disturbance rejection control method based on a cascade extended state observer. It starts with establishing a small-signal model and deriving the transfer function of the SIDO Buck converter. Then, it designs self-disturbance decoupling controllers and series-connected state observers, followed by multiobjective optimization of controller parameters using the particle swarm algorithm. Finally, the control approach is compared with Proportional-Integral-Derivative (PID) control through simulations on a MATLAB platform. The results demonstrate that the proposed controller effectively minimizes cross-coupling effects between the converter outputs and enhances disturbance rejection and robustness.
